PRINTER S CHASE.

Application filed May 3, 1927, Serial No. 188,562. Renewed May 2, 1928.

This invention relates to improvements in printers chases, and has for its primary objeet the provision of a chase provided with improved and adjustable means for holding the type forms in fixed and desired positions within such chases, and to expedite and facilitate the operation of locking the forms in position, enabling the operations to be carried out withthe use of but few, relatively simple and easily applied parts.

Another object of the invention resides in the provision of a chase having the inner marginal edges thereof provided with a plurality of substantially wedge shaped pockets, and in combination with which there is provided a plurality of locking bars having the ends thereof formed with wedge shaped projections, which are adapted to be removably received within said sockets, the arrangement permitting said bars to be quickly and readily associated in a fixedmanner in connection with the ch ase in order to provide quickly and securely for the positioning and locking of the type form or forms and yet, to permit of the ready disassociation of the several parts of the chase when the form is desired to be unlocked or removed.

Vith these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts hereinafter to be more fully described and pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a plan view of a chase formed in accordance with the. present invention,

Figure 2 is a detail perspective view showing one of the socket members carried by the inner marginal edge of the chase.

Figure 3 is a perspective view of one of the locking bars utilized in connection with the chase, showing the wedge shaped projection on the end thereof, which cooperates with the inner marginal edge of the chase,

Figure 4t is a detail plan view showing a slightly modified form of the invention,

Figure 5 is a similar view of a further modification,

Figure 6 is a transverse sectional view on the line 66 of Figure 5, V

Figure 7 is a detail sectional view of a still further modified form of the invention.

Referring more particularly to the drawing the numeral 1 designates a printers chase, which comprises the usual rectangular frame.

In this instance, however, the inner marginal edgcof the chase is provided with a plurality of dove tailed slots 2 in which is securely positioned a plurality of correspondingly formed socket members 3. These members are preferably formed from metal and may be welded, if desired, to the frame bars of the chase or may be integrally formed therewith. Each of the socket members 8 is provided with a substantially wedge shaped socket 4 which opens to one side of each of said members, as shown more particularly in Figure 2.

In combinationwith the socket members I employ a plurality of locking bars 5, which may be of any desired length. In the present instance one of these bars has-beenshown extending longitudinally of the chase from one side or to the other thereof, and another bar has been illustrated as extending from one edge of the chase and engaging with the other of said locking bars. It is obvious, however, that the bars may be of any desired length so as to cooperate with the wedge shaped socket members 3. Each bar, however, has its 0pposite ends formed with wedge shaped projection's 6, which are receivable within the sockets/l of the members 3 carried in connection with th chase. Similar socket members 3 are carried by the opposite edge portions-of the longitudinally extending locking bar 5, all of said socket members are of identical construction. I 7

It will be seen that when it is desired to assemble and position a type form within the chase the longitudinally extending locking bar is'moved laterally, after being positioned within the limits of the frame, so that the projections on the ends of said locking bar will enter the corresponding and aligned sockets l of opposed socket members 3. The longitudinally extending locking bar is then prevented from losing its position by means of the short transversely extending locking bar, which has its opposite projection 6 engaged with one of the socket members 3 of the chase and its other projection engaged with an aligned socket member 3 provided upon an edge of the longitudlnally extending locking bar. The type form 7 is then positioned against said locking bars and is held in place by means of the usual printers furniture 8 which, in turn, is pressed against the form 7 and the bars 5 by means of the usual expansible quoins 9.

In view of the foregoing it will be seen that i the present invention provides a chase which and quoins to a very great extent and at the same time provides for permanency and security 1n the positioning of the form. I/Vhen locked the parts of the chase are firmly associated and loss of position is precluded.-

In the form of the invention set forth in Figure 4 the socket member corresponds in all respects to the socket member 3, with the exception that the entering side of the socket member is inwardly inclined or re cessed as at 11, and the corresponding end 12 of the locking bar is formed to register exactly with this inwardly disposed recess of the member 10. theconstruction preventing undue longitudii'ial separation of the locking bar from the associated socket member. In other words the .iocking bar can be moved in but one direction to disconnect the same from its complement-a1 socket member.

In the form of the invention disclosed in Figures 5 and 6 the socket member 13 includes a pair of spaced lugs 14 which are provided with the sockets 4. The locking bar is formed to include apair of spaced projections 15 of Wedge form, which are receivable within the sockets provided in the spaced lugs. This construction provides for a greater degree of strength and mechanical securities. In the form of the invention disclosed in Figure 7 the socket member includes wedge shaped sockets 16 on the opposite sides thereof, permitting of the application of the locking bar from either side of the socket member. I

Other minor changes may be made without departing from the spirit and scope of the invention as claimed.

That is claimed is:

1. In a printers chase, a frame structure including a plurality of open ended wedge shaped sockets, and a locking bar having the opposite ends thereof provided with wedge shaped projections removably positioned within said socket.

In a printers chase, a frame, a plurality of socket members rigidly positioned to extend from the inner edges of said frame, a locking bar, and a plurality of wedge shaped proj ctionsprovided upon the end of said locking bars and removably receivable within the socket of said members.

3. Ina printers chase, a frame structure having the inner edges thereof provided with a plurality of spaced openings of dove tail form, socket members of corresponding form ri idly positioned within said opening and extending. inwardly from the inner edges of said frame structure, and a locking bar provided with wedge shaped projecting tongues on the opposite ends thereof and adapted to be removably received within the sockets of said members.

4. In a printers chase, a frame having the inner edge thereof provided with a dove tail opening, a socket member having abrace portion shaped to conform to the Wallsof said opening, said member being arranged to project inwardly from the frame structure, the inwardly projecting portion of said member being provided with an open sided wedge shapedpocket, and a locking bar provided at one end with a wedge shaped tongue removably receivable within said pocket.

In a printe -"s'chase, a frame structure including a plurality of rigidly positioned members extended from the inner edges of said frame, -a locking bar, and Wedge and socket connections between said members and the-opposite ends of said bar.

In testimony whereof I affix my signature.
